IMPROVEMENT IN COFFEE-POTS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, RICHARD H. Korma, ofLockport, in the county of Niagara and the State of New York, haveinvented a new and improved Coffee-Pot and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being bad to the accompanying drawing forming part of thisspecification, in which- Figure 1 is a vertical-section illustrating myapparatus when but a single spouting-tube is employed.

Figure 2 is a similar section illustrating the same with twospouting-tubes.

Similar letters of "reference in the accompanying drawing indicatecorresponding parts.

This invention relates to that class of coffee-pots which contain adetachable apparatus consisting of a steam-generating chamber at thebottom, a drippingchamber at the top, and a tube connecting thesteamgenerator with the dripper.

My invention consists of an improved construction of such apparatus,which renders it. less expensive and more convenient and effective thanheretofore.

In the drawing-.

A is the body of the, coffee-pot, of any suitable shape;

B is the steam-generating chamber G is the chamber containingtheextract;

. D is the dripping-chamber;

E is the tapering-tube connecting the steam-generating with thedripping-chamber;

F is the nose or spout of the coffee-pot, provided with a cap, f, toprevent the escape of the aroma;

G is the handle;

H is a hinged bail for convenience in handling the coffee-pot, and forfastening down the cover when necessary; and

I is the cover provided with a fixed bail, t, which, when the cover ison, is designed to stand at right angles with the hinged bail.

The inverted cup, b, which forms the steam-cham her, and the tube E areconnected together. and as a whole are readily removable from thecofiee-pot to facilitate its cleansing or to allow of its use for otherpurposes.

The tube E extends below the top of chamber B, nearly to'the bottom ofthe colfee-pot, so that the steam will rise above its open end and onlyboiling water will be carried up through it; my object being to make theextract by means of a jet or jets of boiling water, and not by a jet ofsteam alone, nor steam mingled with a small quantity of water, asheretofore.

The water being thus forced up by the pressure-of steam in the upperpart of chamber B is sprayed over the whole snrfaceot' the coifee inchamber D by the action of a deflector, an, arranged directly above theopen end of the tube E, as shown.

When only a single tube, E, is employed, as represented in fig. l, Imake the deflector in the shape of an inverted cone soldered to theunder side of the cover I, with its apex directly over and close to thecenter of the mouth of tube E, in which case the jet of water impingingagainst the cone will be das'hed in a sheet of spray equally in everydirection.

When two tubes, E, are employed, arranged near the walls of thecotleepot, as represented in fig. 2, I prefer to make an independentcone, having a small handle, n, and insert it in the chamber, its, edgeresting upon a wire flange or ledge, a, solde'red around the walls ofthe chamber, and its inclined roof directly over and close to thetops ofthe tubes, in which case its action upon the two jets will result in avery uniform distribution of the boiling liquid over the contents of thechamber.

I prefer the single tube and the inverted conical deflector on accountot' their superior cheapness of construction and their convenience inhandling and cleaning, in allwhich respects-they possess greatadvantages over the old style of. deflector attached directly to thetube and supported by'it.

Both the steam generated in the coffee-potand'the spouting column ofwater may sometimes be sufficiently powerful to raise the cover I andallowthe aroma to escape, if not even to throw the boiling water overthe sides of the coifee-pot. To remedy this I provide the stiff: bail i,attached to the cover,

and the bail H, hinged to cars upon the side of the pot A, and capableof being turned over the bail t", as

showirin fig. 2, so as to lock the cover down.

The hinged bail may be constructed of spring wire and made to curveoutward at the sides, as shown at :qx, fig. 2, so that when thepressure. of the steam becomes so great as to endanger the safety of theapparatus the elastic wire will straighten out and allow the cover torise far enough to permit the escape of some of the steam, when itselasticity will cause it to instantly force the cover down again andclose the vessel steam-tight as before.

Little vertical slots, as, may be made in the rim of the cover to allowthe steam to escape without lifting the cover entirely out of place.

Having thus described my invention,

hat I claim as new therein, and desire to secure by Letters Patent,ise 1. In connection with the chambers B 0 D and tube or tubes E of acofi'ee-pot, the independent conical deflector in, supported by thewalls of the sessei, and=operating in combination with said partsvnbstantialiy as described and for the purposes specithe-latter isconstructed to look over the former as herein set forth, and for thepurposes specified.

3. The outward curving bf said bail H as shown a: x, whereby it is madeto operate as a spring when employed incombination with 'the cover I ofa coffee-pot, 'substantieiiy as described and for the purposes setforth.

4. The slots s's in the cover I of a. cofiee-pot, in combination withthe bails H c, substantially as and for the purposes described.
